Validation of numerical simulations for the reduced freeform bending process using a test bench: Validierung numerischer Simulationen des reduzierten Freiformbiegeprozesses mit einem Prüfstand
2019
Freeform bending provides a wide range of possibilities to design complex bending parts based on tubes as well as on profiles. Currently, common inefficient trial-and-error procedures are used for designing and manufacturing freeform bending parts. Numerous iterations, consisting of subsequent real tests, are needed to achieve accurate parts within the tolerances and with the intended quality. The compensation of deviations during the trial-and-error procedure mostly depends on the operator’s experience instead of defined and transferable methods.
